兰州地区1100例中老年人体检心电图分析

Electrographic analysis in 1100 cases of middle and old people

目的分析中老年人群体检者中心电图异常发生情况。方法 1100例中老年体检者在安静状态下平卧,采用日本光电十二导心电图记录仪,采集心电图。结果 1100例中老年人群中正常心电图632例(57.45%),大致正常心电图220例(20.00%);异常心电图248例(22.54%),其中心律失常62例(5.63%),ST-T改变89例(8.09%),传导阻滞87例(7.63%),心室肥厚10例(0.90%)。传导阻滞主要发生于≥66岁组,以66～70岁组为最高;ST-T改变中≥66岁各组发生率基本相同。结论中老年干部人群中,异常心电图的发生率较高,并以传导阻滞和ST-T改变为主要类型,提示应加强对中老年人群中心血管疾病的预防。

Objective To analyze of the incidence rate of abnormal electrocardiogram （ECG） in the middle and old healthy people. Methods Routine electrocardiogram were recorded with electrocardiograph in 1100 cases of the middle and old people in the time of medical examinations. Results Of 1100 people, 632 cases （57.45%）are normal ECG, 220 cases（20.00%）are approximately normal ECG, and 248 cases （22.54%）are abnormal ECG. Among the abnormal, 62 cases（5.63%）have arrhythmia, 89 cases（8.09%）have ST-T change, 87cases（7.63%）have heart conducion block, and 10 cases（0.90%）have ventricular hypertrophy. The heart conducion blocks take place in more than 66 year old people, the highest frequency is fined in the group 66-70 aged. ST-T change have the same incidence in each groups. Conclusions In middle and old people, the incidence of abnormal ECG is higher, among which conducion blocks and ST-T change are common. The study suggests that prophylaxis of cardiovascular diseases should be strengthened in middle and old people.
